@fredisland:
It was not my intention to hide the table of content and the attached "Scan by ACME". If this was my goal, I would have deleted also the additional page at the end.

In fact the lost stuff is due to the fact, that I had to rewrite the file with pdftk, to make it parseable by the archive.org engine. Otherwise it was just all shown as blank pages.

About "intellectual honesty". I don't think that scanning other peoples work does give you any kind of "copyright". I don't care about who scanned it, I give credit to the author who wrote the book in the first place. And BTW I also saw stuff I scanned and put on archive pop up on ACME. I don't care about this. It's not my work, it was scanned in few minutes.

My only goal is to make out-of-print books from decades ago available in a proper online-library, so the information is not lost. I'm not interessted in any "fame" or "donations" and I don't think scanning old books is something one should expect much credit for.

Un ouvrage scanné par ACME https://acpc.me.
Non seulement le crédit a été enlevé, mais la table des matières a aussi subi le même sort.
L'honnêteté intellectuelle n'a jamais tué personne, merci d'y penser la prochaine fois !
